U.S. secretly tracked billions of calls for decades

The U.S. government started keeping secret records of Americans’ international telephone calls nearly a decade before the Sept. 11 terrorist attacks, harvesting billions of calls in a program that provided a blueprint for the far broader National Security Agency surveillance that followed. For more than two decades, the Justice Department and the Drug Enforcement Administration amassed logs of virtually all telephone calls from the USA to as many as 116 countries linked to drug trafficking, current and former officials involved with the operation said. The targeted countries changed over time but included Canada, Mexico and most of Central and South America.

Federal investigators used the call records to track drug cartels’ distribution networks in the USA, allowing agents to detect previously unknown trafficking rings and money handlers. They also used the records to help rule out foreign ties to the bombing in 1995 of a federal building in Oklahoma City and to identify U.S. suspects in a wide range of other investigations. The Justice Department revealed in January that the DEA had collected data about calls to “designated foreign countries.” But the history and vast scale of that operation have not been disclosed until now.

The now-discontinued operation, carried out by the DEA’s intelligence arm, was the government’s first known effort to gather data on Americans in bulk, sweeping up records of telephone calls made by millions of U.S. citizens regardless of whether they were suspected of a crime. It was a model for the massive phone surveillance system the NSA launched to identify terrorists after the Sept. 11 attacks. That dragnet drew sharp criticism that the government had intruded too deeply into Americans’ privacy after former NSA contractor Edward Snowden leaked it to the news media two years ago.

The DEA program did not intercept the content of Americans’ calls, but the records — which numbers were dialed and when — allowed agents to map suspects’ communications and link them to troves of other police and intelligence data. At first, the drug agency did so with help from military computers and intelligence analysts.
